WASHINGTON (WUSA9) -- A radio ad that highlights a letter calling for the Redskins to change their name will air in D.C. leading up to the game against the Chiefs.

The letter is the latest from the Oneida Indian Nation, the group behind the "Change the Mascot" campaign.

More than 60 clergy members have signed the letter to the NFL and Dan Snyder calling for the Redskins to change their name, according to Oneida.

The latest ad will air on Washington's WTOP-FM (103.5) and WPRS Praise-FM (104.1) before the Chiefs game.

"Faith leaders and organizations from a variety of faith backgrounds are increasingly voicing their disapproval of the team's name and making it clear that the time to change the name is now," said Oneida Nation Representative Ray Halbritter. "These clergy leaders have sent a powerful message to the NFL that no group deserves to be treated as the target of a hurtful racial slur, and that Native Americans should be treated as what we are: Americans."

Oneida has aired similar ads in Washington and all cities where the team has played road games throughout the NFL season.
